科学家发明特殊玻璃可以瞬间由透明变不透明

站长搜索讯据国外媒体报道，哈佛大学的科学家们发明了一种特殊的玻璃，这种玻璃可以在电流作用下在透明、半透明和不透明之间转换。

科学家们以前也曾开发过能够由透明转换成不透明的可调性玻璃，它们主要由纳米晶体和金属纳米结构的材料构成。但是它们的造价极其高昂，而且生产难度很高。

哈佛大学约翰鲍尔森工程技术与应用科学学院的研究员教授大卫·克拉克（David Clarke）和博士后研究员塞缪尔·施安（Samuel Shian）声称，他们研究出一种新的玻璃材料，不但能够很快由透明转换成不透明，而且造价相对低廉。他们已经在学术杂志《光学快报》上发表了一篇论文，介绍了自己的研究成果。

这种新型玻璃由三层材料组成，中间一层是普通玻璃，上下两层为一种透明和柔软的弹性纤维材料。这三层材料的表层均被敷设了一个银纳米线构成的涂层，因此这种新型玻璃的生产工艺比原先的可调性玻璃要简单得多。

原先的可调性玻璃是利用一种被称为真空镀膜的技术生产出来的，需要给玻璃基材小心谨慎地镀上一层特殊材料分子。

克拉克在声明中解释说：“因为新的生产工艺是一种物理变化而不是化学变化，因此利用这种工艺来生产可调性玻璃要简单得多，生产成本也相对低廉。”

就材料本身而言，纳米线非常细小，不会反射光线，因此不会被肉眼观察到。但是如果给玻璃通上电流，纳米线就会发生运动，彼此靠拢。从而导致弹性纤维收缩汇聚，造成光散射现象，整块玻璃就会在一秒之内变成彩色。

如果加大电流强度，玻璃就会变成完全不透明的状态。

他们将变形后的弹性纤维涂层比作池塘表面的冰层。他们说：“如果结冰后的池塘表面平滑，你就能透过冰层看到池塘下面的情况。但是如果冰层上出现很多裂痕，你就看不透了。”

哈佛大学已经为这项技术申请了专利，克拉克和施安正在努力开发一种更薄的弹性纤维涂层，这样就能降低让玻璃变成不透明状态时所需的电压。（林靖东）
